Investigational drug(s) / intervention(s)
Silver nanoparticlesuncoated titanium miniscrews
Silver nanoparticles: Patients will receive silver-hydroxyapatite nanocoated titanium miniscrews.These miniscrews will be placed in the maxillary bone for en masse retractonof the upper anterior teeth.
uncoated titanium miniscrews: Patients will receive conventional uncoated titanium miniscrews of the same dimensions and design as the intervention of the group1, but without nano-coating.
Study summary
study will be directed to evaluate silver-hydroxyapatite nano-coated versus uncoated orthodontic miniscrews for en masse retraction of the upper anterior segment.
